HANGER FOR TROLLEY-WIRES.

SPECIFICATION forming part of Letters Patent No. 464,411, dated December 1, 1891.

i Application filed July 17, 1890. Serial No. 359,084. (No model.)

To al? whom t may concer-.11,.-

Be 1t known that ILTHOMAS E. ADAMS, a

Citizen of Cleveland, in the county of Cuyaproved hanger of such construction that the trolley-wire shall be effectually insulated fro m vthe cross or span wire.

A further object is to so construct `the hanger that the trolley-shoe traversing the trolley-wire will not be deviated from its line of travel.

A further object is to produce a hanger conn structed in such manner that the parts or sections thereof` may b e 'easily and quickly as-V sembled.

A further object is to produce a hanger for trolley-wires having` a removable clip for securlng said wire to the hanger.

Vth these objects in view the invention consists in certain novel features of construction and combinations Vand arrangements of parts, as hereinafter set fortl1,'and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of my improvement partly in section. Fig. 2 is a sectional view on the line :c of Fig. l. Fig. 3 is a sectional view on the line y 'y of Fig. 1. FigA is an elevation of a modified form of the invention. Fig. 5 is a View on the line e e' of Fig. 4. Fig. 6 is an elevation of another form of hanger. Fig. 7 is a view on the line w lw of Fig. 6. Fig. 8 is an elevation of another form of the invention. Fig. 9 is aview on the line o o of Fig. 8. Figs. 10 and ll are views of modifications of the insulator-shell.

A represents a hollow metallic shell having a shank b located therein, said shank vbeing provided with two anges or plates ce, one

above the other.- The shell is closed by means of a plate B, from which flanges Y Z depend,

and which may be of any suitable material. The anged shank b is preferably cast in a core in the shell Ain a manner similar to that of casting the clapper iu a Sleigh-bell. The core is then removed through an opening cl in the plate B and insulating material forced or run in the shell and made to envelop the upper portion of the sha-nk b and flanges c of the shank and insulate the same from the shell, the flanges or plates c producing in the insulating material a double canopy.

Instead of making the shell A and plate B of a single piece of metal, they may be made in two parts, as shown in Figs. 10 and ll. shown in Fig.r lO, the shell A is provided interiorly with screw-threads adapted to receive similar screw-threads in the periphery of the plate B, whereby said plate B maybe removably attached to the shell; or, if desired, the plate B maybe secu-red to the shell by means ofApins, as shown in Fig. 11, or by means of solder.

` The shell A isl provided on its top with hooks 1S, by means of which the device may be supported by-a cross-wire. The top of the shell is recessed for the reception of a wedge or key 20, whereby the shell will be maintained in position on the cross-Wire by means of said wedge. As shown in Figs. 10 and 11, the top of the shell may be provided with a screwthreaded recess 22 for the reception of a screw 23, adapted to `bear at its top on the crosswire. The lower end of the shank b projects downwardly from theA center of thev shell A and is bifurcated at its lower end to produce a slot or recess f, the arms producing said recess having a perforation g made in them at y right angles to the slot or recess f. Inserted loosely in the slot or recess f is a stem h of a bracket or hanger B', secured to said stem by means of a removable key h', said hanger being made with arms B2, which terminateat the base of the stem h in shoulders 2'. The lower edge of the bracket or hanger B is provided with a recess j, and made in said lower edge of the bracket or hanger and extending from end to lend thereof is a groove la.' A trolley-Wire C is inserted inthe groove 7c, and at the center of vthe bracket or hanger said trolley-wire is forced into and made to neatly IOO till the recess j. A clip or strapD is made to m of the bracket or hanger and rests at its bottom on the shoulders i of said bracket or hanger. By means of this nut E the strap or clip may be tightened and made to hold the trolley-wire securely to the bracket or hanger B.

In order to preventlateral movement of the strap or clip D on the bracket or hanger B', said bracketor hanger is provided on opposing faces with tongues n, adapted to enter grooves' o in the inner faces of the clip or strap D.

In the form of niyinvention shown in Figs. 4 and 5 the bracket or hanger B is provided with a curved shank 1, the upper ends of the clip or strap D terminating in flanges 2 in proximity to the shoulder 3, formed by the` shank 1. Placed over the shoulder 8 is a yoke 4,' having inwardly projecting flanges 5, adapted to receive the flanges 2 of the clip or strap D. The yoke 4 is provided in its center with a screw-threaded perforation 6 for the reception of a similarly-threaded bolt 7, the head of .which is provided with a series of sockets or perforations 8 for the reception of a suitable tool by means of which to operate it. The lower end of the bolt 7 bears in a socket 9 in the shoulder 3 of the bracket or hanger B', so that when said bolt is screwed down the trolley will be securelytclamped to the bracket or hanger B.

In the form of the invention shown in Figs. 6 and 7 the bracket or hanger B' is extended downwardly at its center and made to produce alip 10, adapted to extend one-half Way around the trolley-wire, as most clearly shown in Fig. 7, and thus produce one half of the clip, the other half of the clip being formed by a plate 11, having a lip 12. The plate 11 is secured to the bracket by means ot re'mov able rivets or screws 13.

In the modification shown in Figs. 8 and 9 the shank of the bracket or hanger B is screwthreaded to enter'the shank b. The clip or strap D in this forni of the invention is composed of two plates 14 15 and a central block 16, secured to the lower ends thereof and adapted to fill the depression in the trolleywire. The plates 14 15 are detachably secured to the bracket by means of bolts or screws 17.

Having fully described my invention, what I claim as new, and desire to secure by Letters Paten t, is-

metallic shell and insulating material adapt ed to fill said shell, of a shank, and flanges or plates projecting from said shank and embedded in the insulating material in the shell, substantially as set forth.

4. lIn an insulator, the combination, with a metallic shell and insulating material adapted to till said shell, of a shank, flanges or plates projecting from said shank and embedded in the insulating material, and hooks on said shell adapted to receive a supporting-wire,

substantially as set forth.

5. In an insulator, the combination, witha metallic shell, of insulating materialinsaid shell, a iianged shank embedded in said insulating material, hooks on said shell for the reception of the wire or Stringer, and awedge or key inserted beneath the wire or Stringer and adapted to prevent the escape of the hooks on the shell from the wire or stringer, substantially as set forth.

6. vThe combination, with an insulator, of a hanger for supporting a trolley-wire loosely connected with said insulator, the loose connection between said insulator and hanger being removable, substantially as set forth.

7. The combination, with a hanger, of a removable clip adapted to embrace said hanger and secure a trolley-wire thereto, and a nut adapted to secure the free ends of said clip, substantially as set forth.

S. The combination, with a hanger having a recess in the center of its lower edge and a groove in said lower edge extending fromk end to end of the hanger, of a clip for securing a trolley-wire in said recess and groove, said clip being detachably secured to the hanger, substantially as set forth.
